Deepa Mehta

Mehta was born in Amritsar, Punjab near the militarized border of Pakistan and experienced firsthand the impacts brought forth by the Partition of India. She describes learning about warfare from citizens of Lahore, stating "Even when I was growing up in Amritsar, we used to go every weekend to Lahore, so I just grew up around people who talked about it incessantly and felt it was one of the most horrific sectarian wars they knew of."

Her family moved to New Delhi while she was still a child, and her father worked as a film distributor. Subsequently, Mehta attended Welham Girls High School, boarding school in Dehradun on the foothills of Himalayas. She graduated from the Lady Shri Ram College for Women, University of Delhi with a degree in Philosophy.

Mehta notes how her reception to film transformed and changed as she got older and was exposed to different types of cinema, which ultimately influenced her to become a filmmaker herself. She states:

"When I was growing up in Delhi and I went to university in Delhi, I used to watch [Indian] films. I grew up with a very healthy dose of Indian commercial cinema. My father was a film distributor, so from a very young age I saw commercial Indian cinema. But once I went to university, or even my last year of school, I really started watching and enjoying Satyajit Ray and Ritwik Ghatak and had exposure to non-Hindi cinema and non-Hollywood cinema. At university, I was also exposed to directors like Truffaut and Godard. There was also intense exposure to Japanese cinema. So, Ozu, Mizoguchi."After graduating Mehta began working for a production company that made documentary and educational films for the Indian government. During the production of her first feature-length documentary focusing on the working life of a child bride, she met and married Canadian documentary filmmaker Paul Saltzman, who was in India making a film. She migrated to Toronto to live with her husband in 1973, and was credited in some of her early films as Deepa Saltzman.

Once in Canada, Mehta and Saltzman along with Mehta's brother Dilip started Sunrise Films, a production company, initially producing documentaries but moved into television production creating the television series Spread Your Wings (1977–79) about the creative and artistic work of young people from around the world. Additionally, Mehta directed several episodes of the Saltzman produced CBC drama Danger Bay (1984–90).

Mehta also directed the documentaries At 99: A Portrait of Louise Tandy Murch (1975) and Traveling Light (1986), the latter focusing on the work of Mehta's brother Dilip as a photojournalist. Traveling Light would go on to be nominated for three Gemini Awards. In 1987, based on the works of Alice Munro, Cynthia Flood and Betty Lambert, Mehta produced and co-directed Martha, Ruth and Edie. Screened at the Cannes International Film Festival, it would go on to win the Best Feature Film Award at the 11th International Film Festival in Florence in 1988.

In 1991 she made her feature-film directorial debut with Sam & Me (starring Om Puri), a story of the relationship between a young Indian boy and an elderly Jewish gentleman in the Toronto neighbourhood of Parkdale. It broke the record at the time for the highest-budgeted film directed by a woman in Canada at $11 million. It won Honorable Mention in the Camera d'Or category of the 1991 Cannes Film Festival. Mehta followed this with her film Camilla starring Bridget Fonda and Jessica Tandy in 1994. In 2002, she directed Bollywood/Hollywood, for which she won the Genie Award for Best Original Screenplay.

Mehta directed two episodes of George Lucas' television series The Young Indiana Jones Chronicles. The first episode, "Benares, January 1910", aired in 1993. The second episode was aired in 1996 as part of a TV movie titled Young Indiana Jones: Travels with Father.

Mehta directed several English-language films set in Canada, including The Republic of Love (2003) and Heaven on Earth (2008) which deals with domestic violence and has Preity Zinta playing the female lead. It premiered at the 2008 Toronto International Film Festival. Also in 2008 Mehta produced the documentary The Forgotten Woman, directed by her brother Dilip.

In 2005 it was announced that Meetha would film an adaptation of Shilpi Somaya Gowda’s Secret Daughterwith a cast including Amitabh Bachchan, John Abraham, Seema Biswas and Terence Stamp in and Nandita Das, Manisha Koirala, Mahima Chaudhry, and Padma Lakshmi in supporting roles. The film, titled Exclusion, was to have music by A. R. Rahman, and cinematography and editing by Giles Nuttgens and Colin Monie respectively. It would have been based on the Komagata Maru incident, an incident where Canada turned away 397 Indian dissidents as a part of a policy to keep Canada racially white. But, although the project was postponed for many years, the film remained unrealised.

In 2015, Mehta wrote and directed Beeba Boys. It premiered at the 2015 Toronto International Film Festival.

In 2016, Mehta directed the drama film Anatomy of Violence, which uses fiction to explore the root causes which led to the 2012 Delhi gang rape and murder.

On 29 October 2020, Telefilm Canada announced that Mehta's film Funny Boy (2020) would represent Canada in the Academy Awards race for best international feature film. However, the film was disqualified by the Academy Awards as its mix of English, Sinhala and Tamil dialogue did not surpass the required percentage of non-English dialogue.

At the 9th Canadian Screen Awards in 2021, Mehta won the Best Director award for Funny Boy. She and cowriter Shyam Selvadurai also won the award for Best Adapted Screenplay.

In November 2021, Variety announced that Mehta is set to direct a film adaptation of Avni Doshi's novel Burnt Sugar, with Ben Silverman's Propagate Content producing the film.
